Definitions

  • the invention broadly relates to (i) pads of pressure sensitive adhesive tape sheets, (ii) dispensers for tape sheet pads, and (iii) methods of dispensing individual tape sheets from tape sheet pads.
  • pressure sensitive adhesive tapes capable of connecting or joining two surfaces (e.g., adhering a sheet of paper onto a tabletop) are well known.
  • #810 ScotchTM MagicTM brand transparent tape manufactured by Minnesota Mining and Manufacturing Company, St. Paul, Minn. is readily available from numerous retail outlets.
  • Such pressure sensitive adhesive tapes, including #810 ScotchTM MagicTM brand transparent tape are generally available as a continuous roll of tape capable of being conveniently dispensed from any of a number of manually-operated roll-type tape dispensers, such as those disclosed in U.S. Pat. No. 4,928,864 and D116,599, having a cutting edge located on the dispenser for cutting the tape into strips of the desired length.
  • Post-it® brand notes and Post-it® brand flags available from Minnesota Mining and Manufacturing Company of St. Paul, Minn., require a coating of releasable pressure sensitive adhesive only along one end of the substrate, and can therefore be conveniently dispensed from a container by alternating the adhesive end of each sheet/flag in the stack between opposed first and second ends of the stack (e.g., forming a Z-stack of sheets).
  • a stack of Post-it® brand flags and associated shuttling dispenser is disclosed in U.S. Pat. No. 4,770,320.
  • a pad of W-stacked sheets and associated dispensers are disclosed in U.S. Pat. Nos.
  • U.S. Pat. No. 5,401,547 discloses a pad of superimposed adhesive tape strips wherein the adhesive layer of each tape strip is releasably adhered to an adjacent tape strip at a first adhesion level at a first end and a second adhesion level at a second end (i.e., differential release), and sequential tape strips are longitudinally reversed so as to align the first end of each tape strip with the second end of an immediately overlaying and an immediately underlying tape strip.
  • a preferred manner of achieving such differential release disclosed by '547 is to coat the entire surface area of a first major surface of each strip with a pressure sensitive adhesive and coat the second end portion of the second major surface of each tape strip with a low adhesion backsize.
  • Such an alternately stacked pad of differential release tape strips can be conveniently dispensed from an associated dispenser with a single hand while maintaining a continuous coating of an aggressive pressure sensitive adhesive on the substrate.
  • the pads disclosed by '547 must comply with narrow quality control standards in order to achieve the sliding action required between adjacent tape strips for proper dispensing while preventing fanning of the stacked strips (i.e., preventing the tape strips from accidentally and unintentionally sliding relative to one another before each strip is dispensed). Furthermore, as described in Blackwell et al., when the necessary differential release requirement is achieved by the application of a premium low adhesion backsize on one end of the tape strips and a basic adhesion backsize on the other end, that portion of the tape strip coated with the premium low adhesion backsize does not consistently maintain any written indicia.
  • the tape sheets in a group of any three sequentially stacked tape sheets are referenced as an overlying tape sheet, an intermediate tape sheet, and an underlying tape sheet with the adhesive layer of the overlying tape sheet adhered to the intermediate tape sheet, and the adhesive layer of the intermediate tape sheet adhered to the underlying tape sheet.
  • a first embodiment of the novel stacked pad of adhesive tape sheets comprise a plurality of superimposed tape sheets wherein: (i) the tape sheets are formed from a substrate with an area of differential release which extends less than the full length and width of the substrate, (ii) the second major surface of the substrate includes a layer of an adhesive, (iii) sequential tape sheets are configured and arranged with the area of differential release alternating between first and second corners of the sheets, and (iv) the adhesive layer of each tape sheet is releasably adhered to an adjacent tape sheet at a higher adhesion level, except for the area of differential release which adheres to an adjacent tape sheet at a lower adhesion level.
  • the relative release forces of the first and second adhesion levels are effective for consistently causing the area of an intermediate tape sheet adhered to an immediately underlying tape sheet at the second adhesion level to release from the immediately underlying tape sheet before an overlying tape sheet is completely released from the intermediate tape sheet.
  • a second embodiment of the novel stacked pad of adhesive tape sheets comprise a plurality of superimposed tape sheets wherein: (i) the tape sheets are formed from a substrate with an area of differential release, (ii) the second major surface of the substrate includes a layer of an adhesive, (iii) sequential tape sheets are configured and arranged with the area of differential release alternating between different areas on the sheets, and (iv) the adhesive layer of each tape sheet is releasably adhered to an adjacent tape sheet at a higher adhesion level, except for the area of differential release which adheres to an adjacent tape sheet at a lower adhesion level.
  • Positioning of the areas of differential release and the relative release forces of the higher and lower adhesion levels are effective for consistently causing the area of an intermediate tape sheet adhered to an immediately underlying tape sheet at the lower adhesion level to release from the immediately underlying tape sheet before an overlying tape sheet is completely released from the intermediate tape sheet when the overlying tape sheet is dispensed at a peel angle of greater than 90°.
  • a third embodiment of the novel stacked pad of adhesive tape sheets comprise a plurality of superimposed tape sheets wherein: (i) the tape sheets are formed from a substrate with an area of differential release, (ii) the second major surface of the substrate includes a layer of an adhesive, (iii) sequential tape sheets are configured and arranged with the area of differential release alternating between different areas on the sheets, and (iv) the adhesive layer of each tape sheet is releasably adhered to an adjacent tape sheet at a higher adhesion level, except for the area of differential release which adheres to an adjacent tape sheet at a lower adhesion level.
  • Positioning of the areas of differential release and the relative release forces of the higher and lower adhesion levels are effective for consistently causing the area of an intermediate tape sheet adhered to an immediately underlying tape sheet at the lower adhesion level to release from the immediately underlying tape sheet before the overlying tape sheet is completely released from the intermediate tape sheet within the area where the intermediate tape sheet is adhered to the immediately underlying tape sheet at the higher adhesion level.
  • a first embodiment of the novel technique for dispensing adhesive tape sheets from the stacked pads of adhesive tape sheets of this invention includes the sequential steps of (i) pulling the overlying tape sheet away from the pad so as to effect peeling of the overlying tape sheet from the intermediate tape sheet in a peel direction which is never parallel to the substantially linear interior boundary of the area of differential release between the intermediate tape sheet and the underlying tape sheet, and (ii) continuing to pull the overlying tape sheet away from the pad to sequentially effect (a) release of the intermediate tape sheet from the underlying tape sheet over the area of differential release between the intermediate tape sheet and the underlying tape sheet, and (b) complete separation of the overlying tape sheet from the intermediate tape sheet.
  • a second embodiment of the novel technique for dispensing adhesive tape sheets from the stacked pads of adhesive tape sheets of this invention includes the sequential steps of (i) pulling the overlying tape sheet away from the pad so as to effect peeling of the overlying tape sheet from the intermediate tape sheet, and (ii) continuing to pull the overlying tape sheet away from the pad to sequentially effect (a) release of an area of the intermediate tape sheet from the underlying tape sheet wherein the area of release extends less than the full length and less than the full width of the intermediate tape sheet, and (b) complete separation of the overlying tape sheet from the intermediate tape sheet.

  • the phrase “differential release,” when used to characterize an adhesive tape sheet, means adherence of an adhesive tape sheet to an underlying tape sheet at a different adhesion level.
  • tail off when used to describe the defective dispensing of tape sheets from a tape sheet pad, refers to those situations where an overlaying tape sheet separates from an intermediate tape sheet without lifting the area of differential release between the intermediate tape sheet and an underlying tape sheet a distance sufficient to permit the intermediate tape sheet to engage a dispenser and remain spaced from the underlying tape sheet so as to facilitate subsequent dispensing of the intermediate tape sheet.
  • Tail off includes both the phenomenon known as “walk off” (i.e., the overlaying tape sheet separates from an intermediate tape sheet without lifting an area of the intermediate tape sheet) and the phenomenon known as “fall back” (i.e., the area of the intermediate tape sheet adhered to an underlying tape sheet at a differential release is separated from the underlying tape sheet during dispensing of the overlying tape sheet, but does not separate far enough to prevent the intermediate tape sheet from returning to the pad and reengaging the underlying tape sheet when the overlaying tape sheet is separated from the intermediate tape sheet).

  • An intermediate tape sheet subjected to “tail off” is difficult to dispense because a portion of the “tailed off” tape sheet is not properly presented for dispensing and a user must attempt to initiate separation of the “tailed off” tape sheet from the pad by picking at the edge the “tailed off” tape sheet.

  • a length of double-faced adhesive tape 80 is provided between the backing 70 on the tape sheet pad 10 for securing the pad 10 into position on the first major surface 111 of the base 110 (i.e., the pad 10 does not detach from the base 110 during dispensing of individual tape sheets 20 from the pad 10 ).
  • the exposed surface (unnumbered) of the double-faced adhesive tape 80 can be covered with a release liner 90 prior to attachment of the pad 10 to the base 110 of the dispenser 100 .
  • the dispenser 100 permits the consistent dispensing of large individual tape sheets 20 from a tape sheet pad 10 over a wide range of peel angles ⁇ , including peel angles ⁇ in excess of 90° and even in excess of 135°, a wide range of release forces for both the area of differential release and the area of basic release, and a wide range in the ratio of superior release force (SRP) to basic release force (BRF).
  • SRP superior release force
  • BRF basic release force
  • a tape sheet pad 10 constructed within the general parameters set forth below in Table One can generally be dispensed with minimal failure (i.e., without multi-sheet dispensing and/or tail off) and with a consumer friendly release force when dispensed at peel angles ⁇ of greater than 90°. It is noted that an increase in either the SRF and/or the BRF (i.e., a “tighter” pad 10 of adhesive tape sheets 20 ) generally requires an increase in the ratio of SRF:BRF and/or a decrease in the release length in order to maintain the desired dispensability of the pad. It is also noted that the stiffness and caliper of the substrate 30 can also impact the SRF:BRF ratio capable of preventing tail off.
  • 11 and 12 is initiated by (i) lifting the nonadhesive tab 65 of the leader sheet 60 , (ii) pulling the leader sheet 60 away from the pad 10 so as to cause the uppermost tape sheet 21 to release from the immediately adjacent tape sheet 20 in the area of differential release between the two tape sheets 20 with the leader sheet 60 still attached to the uppermost tape sheet 21 over a portion of the area of differential release between the uppermost tape sheet 21 and the immediately adjacent tape sheet 20 , (iii) continuing to pull the leader sheet 60 so as to pull the released area of the uppermost tape sheet 21 towards the associated tab 120 on the dispenser 100 with a distal end portion (unnumbered) of the released area of the uppermost tape sheet 21 extending beyond the associated tab 120 , and (iv) completing dispensing of the leader sheet 60 by pulling on the leader sheet 60 until the leader sheet 60 completely separates from the uppermost tape sheet 21 , with the distal end portion of the released area of the uppermost tape sheet 21 contacting and resting upon the associated tab 120 so as to prevent the released area of the upper
  • subsequent tape sheets 20 can be individually dispensed from the pad 10 by repeating steps (ii) through (iv), wherein a dispensing set of an overlaying tape sheet 25 o , intermediate tape sheet 25 i and underlying tape sheet 25 u are involved rather than a leader sheet 60 , uppermost tape sheet 21 and adjacent tape sheet 20 , respectively.
  • the intermediate tape sheet 25 i can be lifted from the underlying tape sheet 25 u in the area of differential release (i.e., area of lower adhesion level) between the intermediate tape sheet 25 i and the underlying tape sheet 25 u before the overlying tape sheet 25 o is completely released from the intermediate tape sheet 25 i in the area of higher adhesion level (i.e., the entire surface area minus the area of differential release) between the intermediate tape sheet 25 i and the underlying tape sheet 25 u.

  • the pad 10 and dispenser 100 are configured and arranged to permit peeling of the overlaying tape sheet 25 o at a peel angle of greater than 90° and up to a peel angle of 180°. Such peel angles allow dispending of an overlaying tape sheet 25 o at a decreased peel force relative to the peel force observed when peeling an overlaying tape sheet 25 o at a peel angle of 90° or less, and permit a more natural dispensing of large tape sheets 20 .
  • Configuration and arrangement of the pad 10 and dispenser 100 further facilitates dispensing and use of the tape sheets 20 by providing a consistent orientation of the tape sheets 20 relative to the dispenser 100 and allowing a user to readily observe and comprehend such orientation during dispensing of the overlying tape sheet 25 o .
  • This allows a user to innately know which side of the overlying tape sheet 25 o is coated with adhesive 50 and thereby eliminates the prevailing practice observed with prior art tape strips of a user physically touching both sides of a dispensed tape strip in order to ascertain which side of the dispensed tape strip contains the adhesive.
  • a spent pad 10 can be replaced in the dispenser 100 by (i) peeling any remaining vestige of the spent pad 10 from the base 110 of the dispenser 100 (e.g., backing 70 and tape 80 ), (ii) removing the release liner 90 from the replacement pad 10 , (iii) positioning the replacement pad 10 onto the base 110 of the dispenser 100 with the areas of differential release positioned under the tabs 120 and (iv) pressing the properly positioned replacement pad 10 into adhesive engagement with the base 110 of the dispenser 100 .
  • Adhesion to glass is the force required to remove a coated flexible sheet material from a test panel of glass measured at a specific angle and rate of removal. This force is expressed in units force per width of coated sheet.
  • the testing procedure is based upon ASTM D3330-78 and PSTC-1 in which (i) the adhesive tape sheet is applied to the horizontal surface of a clean glass test plate with at least 12.7 lineal cm of the sheet in firm contact with the glass plate using a 2.2 kg hard rubber roller to apply the sheet, (ii) the free end of the sheet is doubled back nearly touching itself so the angle of removal will be 180°, (iii) the free end of the sheet is attached to an adhesion tester scale, (iv) the glass test plate is clamped into the jaws of a tensile testing machine which is capable of moving the plate away from the scale, and (iv) the plate is moved away from the scale at a constant rate of 2.3 meters per minute.
